Charge qubits are promising quantum logical elements for performing quantum
computation or as intermediate states to prepare and read other qubit
realizations such as spin or flux. Instead of idealizing the charge qubits
at the outset and using standard quantum circuit theory, we use the extended
Hubbard model as a first-principles model of charge qubit dynamics and model
idealized proposals for charge-qubit circuits using this second-quantized
description with short- and medium-range interactions. In particular we
study how one- and two-qubit gates would perform for realistic systems, and
we apply our theory to teleportation of a single charge qubit in a
three-qubit system. We also discuss how to incorporate phonon noise into the
model.
